Coordinate-Based Sound Field Interface for Intuitive Parameter Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with limited technical knowledge find it difficult to set sound field parameters effectively, as they need to specify values point by point without understanding the relation between parameters and the desired sound field attributes.
Innovation Solution
A user interface device with a display unit showing a coordinate axis associated with sound field attributes, allowing users to specify a coordinate value that corresponds to a position on the interface screen, which in turn specifies the values of multiple parameters for signal processing to create the desired sound field.

Engineering Contradiction Analysis
1Measurement precision
If users specify parameter values point by point using traditional interfaces, then parameter setting precision is improved, but ease of operation deteriorates due to lack of understanding about parameter-sound field relationships
Solution Approach 1:
The patent introduces a coordinate system as an intermediary between the user and the sound field parameters. Instead of directly manipulating multiple parameters, users specify a position in the coordinate system, and the system automatically converts this into appropriate parameter values. This mediator layer simplifies the interface while maintaining precise control over the sound field attributes.
Solution Approach 2:
The patent transforms the control interface from direct parameter manipulation to coordinate-based specification. By changing the parameter representation from individual parameter values to a unified coordinate system, users can intuitively control sound field attributes (such as position, size, shape) without needing to understand the complex relationships between multiple underlying parameters.
2Ease of operation
If multiple parameters are allocated to a single coordinate axis, then ease of operation is improved by reducing the number of controls, but device complexity increases due to the need for coordinate-value-to-parameter conversion mechanisms
Solution Approach 1:
The patent merges multiple sound field parameters that share a common attribute (e.g., position, size, shape) onto a single coordinate axis. By combining related parameters into a unified coordinate system, the interface becomes simpler for users while the system handles the complexity of coordinating multiple parameters through the coordinate conversion mechanism.

AI summary
A user interface device includes: a display unit that displays a user interface screen associated with a first coordinate axis, the first coordinate axis corresponding to a first attribute of a sound field and being allocated with a plurality of parameters related to the first attribute; a first specification unit that specifies a coordinate value of the first coordinate axis corresponding to a position in the user interface screen specified by a user; and a second specification unit that specifies a value of each of the plurality of parameters, based on the specified coordinate value.
